The tournament system consisted of a single
round-robin tournament, where the team with most points was crowned champion: however, Brazil and Uruguay finished tied on points, meaning a play-off was required. It was also the first time that a non-
CONMEBOL referee (Robert L. Todd of England) was appointed to a CONMEBOL match. After the match finished 0–0, both captains and Todd agreed to play an
extra time period of two 15-minute halves. When 120 minutes expired with the score still tied 0-0, both captains and Todd agreed to play a second extra time period of two 15-minute halves, meaning the final lasted 150 minutes. This was the longest football match ever in Copa América history, while
Arthur Friedenreich scored the goal that allowed Brazil to win its first international title in the 122nd minute, the latest goal in Copa América history; under current rules, both records will stand indefinitely. == Match details ==
